LM134 Series

Constant Current Source

and Temperature Sensor

FEATURES

DESCRIPTIO

■

1µA to 10mA Operation

The LM134 is a three-terminal current source designed to

operate at current levels from 1µA to 10mA, as set by an

external resistor. The device operates as a true two-

terminalcurrentsource, requiringnoextrapowerconnec-

tions or input signals. Regulation is typically 0.02%/V and

terminal-to-terminal voltage can range from 800mV to

40V.

0.02%/V Regulation

■

0.8V to 40V Operating Voltage

■

Can be Used as Linear Temperature Sensor

■

Draws No Reverse Current

■

Supplied in Standard Transistor Packages

Because the operating current is directly proportional to

absolute temperature in degrees Kelvin, the device will

also find wide applications as a temperature sensor. The

temperature dependence of the operating current is

0.336%/°C at room temperature. For example, a device

operating at 298µA will have a temperature coefficient of

1µA/°C. The temperature dependence is extremely accu-

rate and repeatable. Devices specified as temperature

sensors in the 100µA to 1mA range are the LM134-3,

LM234-3 and the LM134-6, LM234-6, with the dash

numbers indicating ±3°C and ±6°C accuracies, respec-

tively.

APPLICATIO S

■

Current Mode Temperature Sensing

■

Constant Current Source for Shunt References

■

Cold Junction Compensation

■

Constant-Gain Bias for Bipolar Differential Stage

■

Micropower Bias Networks

■

Buffer for Photoconductive Cell

■

Current Limiter

If a zero temperature coefficient current source is re-

quired, this is easily achieved by adding a diode and a

resistor.
